When someone takes the day of school/work, claiming "Sickness" when they are not sick.
Mostly used by Australian Students who have a test or assignment due.
Teacher: Philip?
Philip: Here
Teacher: Jack
*silence
Philip: He decided to chuck a sickie, Sir.
‘The ball hit the ground first. There’s no way that was a catch. I’m not going anywhere.’
‘Give it up, you’re out. Everyone saw it was a catch. Don’t Chuck-a-Trump.’
You had a flat tire, you weren't in auto club, mobile phone was out of batteries, late for work without a note and there were no tools in the car so you chuck a wobbly.
